Harry Manback reckoned this to be so:

Spent an inordinate amount of time last night trying to "beat" the
damned game.

Have you tried it on the Easy difficulty with the Inset Corners starting
position? With cheating, those settings should allow you to win
virtually any deal of the cards (though winning is never automatic, it's
definitely a strategy/planning game).

I've got some pretty old Windows and Mac demo versions that can be
downloaded here if anyone else wants to take a crack at beating the game:

The demo doesn't allow any cheating, so it's tougher to beat...
